1.
in short, blockchain is a community-based technology, which can make value exchange more secure. Blockchain is their name 
therefore, chain operation has a huge impact on the people, creating the greatest value for the enterprise and bringing more convenience to the people
2. Although driven by the influx of capital and talents, the blockchain instry ushered in rapid development, but as an emerging instry, the frequent warning of its security vulnerabilities caused people to worry about the risk of blockchain<
Yu Kequn, director of the national information technology security research center, pointed out that for privacy exposure, data leakage, information tampering, network fraud and other issues, the emergence of blockchain has brought a lot of expectations to people. However, there are still many challenges in the security of blockchain
Yu Kequn said that at present, the blockchain is still in the primary stage, and there are many challenges such as the security of cryptographic algorithm, protocol security, use security, system security and so on
Yan Hanbing, director of the operation Department of the national Internet Emergency Center, also pointed out that if blockchain wants to occupy an important position in the global economy, it must first solve the security problems it faces
Yan Hanbing pointed out that blockchain security issues include many aspects. For example, traditional security issues, including the protection of private key, including the traditional vulnerabilities of application layer software. In addition, there are some loopholes in the new protocol
the data provided by the decentralized vulnerability platform (DVP) also shows the seriousness of blockchain security issues. Wu Jia, head of DVP, revealed that in the week since July 24, DVP has received 312 vulnerabilities from white hat, involving 175 project parties. Including smart contracts, well-known public chains, exchanges and a series of other projects. There are 122 high-risk vulnerabilities, accounting for 39.1% of all vulnerabilities, and 53 medium risk vulnerabilities, accounting for 17% of all vulnerabilities
Li Bin, assistant director of China Information Security Evaluation Center, analyzed that the current blockchain is divided into three types: public chain, private chain and alliance chain. No matter which type, it faces security challenges in algorithm, protocol, usage, time limit and system. What is particularly critical is that the current blockchain is still facing 51% attack problem, that is, nodes can successfully tamper and forge blockchain data by mastering more than 51% of the network examples
it is worth noting that in addition to external malicious attack risk, blockchain also faces the threat of its endogenous risk. Yu Kequn reminded that how to build a complete security application system around the equipment, data, application, encryption, authentication and authority of the application system of the whole blockchain is an important problem that all parties must face
Wu Jia also analyzed that as an emerging instry, employees in the blockchain instry are lack of safety awareness, which leads to the low safety factor of software and hardware related to the blockchain, and there are a lot of security loopholes. In addition, there are many ecological links in the whole blockchain. In contrast, the strength of relevant security employees is scattered, and it is difficult to form a joint force to solve the problem. A systematic solution is needed to meet the above challenges.

3. Blockchain is a technical solution to collectively maintain a reliable database through centralization and distrust. This technical solution allows any number of nodes in the participating system to calculate and record all the information exchange data in the system in a period of time to a data block through cryptography algorithm, and generate the fingerprint of the data block for linking the next data block and checking. All participating nodes in the system jointly determine whether the record is true
blockchain can improve the way of data recording in audit. In the current network audit, although there is an early warning mechanism, it still needs auditors to judge and handle the abnormal records manually; Blockchain can automatically process the abnormal records through whether each node verifies and approves the block and the transaction information in it, whether the network node is attacked, and whether the account book of each node is complete, so as to make real-time audit possible. Auditors can directly access and query the effective information on the blockchain, judge whether the processing is reasonable and make corrections. In the blockchain, timestamps are used to record various transactions and operations, which can achieve historical traceability and tracking, and greatly improve the quality and efficiency of audit
blockchain can change the storage mode of audit data. In traditional audit, data are stored in an audit center server, which not only has the problems of high load and slow running speed, but also is vulnerable to attack; The blockchain audit system is a typical distributed storage, each node has the same backup, which can not only save the high cost and maintenance costs of the server, but also ensure the integrity of the data
semi public private chain can be used for audit. Blockchain can be divided into three forms: public chain, semi open private chain and full private chain. Considering the characteristics of audit instry, it is appropriate to adopt semi open private chain mode. For the audited units and enterprises, some trade secret information is not disclosed, but the pre selected nodes within the group decide the generation of the block. External suppliers can participate in the transaction but not the accounting process. Externally, it provides a third-party query node to query through the open API. In this way, it can not only ensure the internal privacy of the enterprise, but also enable the external auditors to implement real-time audit query.

4. Chongqing jinwowo analyzes the impact of blockchain technology on the instry: blockchain will determine the relationship between people and all the Internet including artificial intelligence. The change of this relationship will have a subversive impact on the mainstream Internet business model and create a new era of decentralization.
5. Teachers from Huo coin University believe that blockchain can be called a "hydrogen bomb" business tool, which binds strong network effect and financial leverage to realize the effective allocation of digital value in space and time. It plays an important role in the development of enterprises. If you want to learn more about blockchain, you can pay attention to them. At present, online live courses are also carried out.
6. First of all, blockchain is likely to become the next important goal of e-commerce, which has been revealed in the larger instry participants. Alibaba has invested heavily in the research and development of blockchain and other large e-commerce companies (such as Wal Mart and Unilever) to cooperate with IBM, a technology giant, to enter the blockchain
secondly, for e-commerce, the smart contract of blockchain allows buyers and sellers to conct direct transactions. Smart contracts can be set to be executed only when specific obligations are fulfilled. For example, the buyer can send the determined price of the proct to the contract in cryptocurrency. The seller sends the proof of ownership to the smart contract and connects the smart contract with the company that transports and sells the proct. Once the seller has fulfilled all the obligations, the smart contract will automatically send the funds to the seller's wallet< Then, e-commerce has encountered setbacks in international transactions. But the company that can create a country and currency agnostic solution with blockchain technology is the request network. This blockchain based platform is eager to create a decentralized platform to provide convenient, fast and secure transactions for B2B, B2C and C2C interactions
finally, another disruptive function of blockchain technology is that it allows non corrupt visualization of the supply chain. We haven't done that yet, because blockchain still needs a lot of adoption, but once this happens, the whole chain reaction of the proct can be directly displayed with a tap of the thumb. Whether the proct is real, organic, fair trade or contains chemicals can be seen directly on its blockchain. Since the blockchain is not corrupt, it allows a completely transparent supply chain, allowing consumers to fully understand the procts they consume
with the progress of technology, blockchain will bring convenience to e-commerce in some other ways

9. Blockchain provides an excellent opportunity for traceability business. Traceability refers to tracking and recording the circulation chain of tangible goods or digital goods. Through the registration of each circulation, it can achieve the goals of information collection and recording from the source, tracing the source of raw materials, proction process, inspection batch, logistics circulation, anti-counterfeiting authentication, optimizing the supply chain according to the traceability information, and providing supply chain financial services. The internal logic of applying blockchain technology to traceability, anti-counterfeiting and optimization of supply chain is very similar to the scenario of data storage, that is, data can not be tampered with and time stamped.
